the Southern Airport Line starting as a bus connection then going to full Light Rail just makes sense especially as the next project off the rank post City Rail Link. The Southern Airport Line fulfils three key aspects lacking in transit to the Airport complex: Connecting Southern Auckland and Howick workers to the Airport whether via Puhinui Station if coming up on the rail line or via Manukau Bus Station if using local South Auckland busses or the bus from Botany Connections to the City Centre, Northern Busway or the Western Line via Puhinui and Britomart Stations on the Southern or Eastern Lines Tourist connections from the Airport to Puhinui Station to then either go north or south on the rail line or to Manukau Bus Station to link up with Inter City busses Getting the Southern Airport Line off the ground would be a good quick win as the City continues to prepare for the Light Rail Line from the North (at least 10 years). With help of Central Government there is no reason to get the Southern Airport Line running by 2020. - voakl.net
